PROS - if you over-rev you will bend a dime a dozen pushrod, easy fix, would probably not break anything else.

CONS - with a high lift cam and hi-po springs you will weaken the stock pushrod and risk the chnce of breaking it under stressful driving situations without ever over -revving the engine. You also risk bending a pushrod and throwing the geometry of the valvetrain off thus causing problems in other areas. Meaning, it is inherently weaker, so there is always a higher risk of bending it and if you do then you also risk damaging other valvetrain parts in the process.

You could go either way. You will be glad you had stockers in if you bend one and can get it fixed before any damage is done, you will look like a genious. Although you look like a boob if for some reason your valvetrain starts making noises after 3 months and you pull the head to find bent valves and pushrods and you know you never over -revved it. Then you have to fix and replace a lot.

There is a compromise. You don't have to go all the way and get chrome moly pr's. You can get new pr's made much stronger than stock which are rated to your springs and cam but not as strong as moly so they should still be the first to bend or break. It's what I do.
Good Luck,
